The Travel 503 delivers over 500 watts of input power and in terms of propulsion is comparable with 1.5 HP petrol outboard.

Its name says it all. With the Travel 503 you can discover the world on water, completely waterproof to IP67. Thanks to the on-board computer with its GPS-based calculation of the remaining range, you always have your own travel guide with you.

The Travel 503 is suitable for inflatables and other small boats.

Like the Travel 1003, the Travel 503 is available in short-shaft and long-shaft versions.

Benefits:

With its integrated lithium batter and its outstanding efficiency, the Travel is the alternative to a small petrol outboard.

Can do everything that a 1.5 HP petrol outboard can, plus it’s environmentally friendlier, quieter, lighter and more convenient

Completely waterproof (IP 67)

On-board computer with GPS-based calculation of remaining range

Solar rechargeable – including during the voyage

Can be easily dismantled for transport and space-saving storage; the outboard on its own weighs only 9 kg

A clean affair: no matter how or where you store your Travel – there’s no risk of leakage or petrol smells

When travelling through water, displacement increases power required in proportion to the cube (third power) of the speed. This means that doubling water speed increases the power required eightfold.

Conversely, it of course also means that only a slight reduction in speed will increase the range attainable significantly. Simply reducing speed by e.g. half a knot has a considerable effect on the remaining range.

Since mental arithmetic to the power of three is quite tricky, the on-board computer of the Travel constantly calculates the remaining range for you. To do this, it combines the consumption data from the motor with the charge level of the batteries together with the speed over water obtained via GPS. This means you can read the remaining range in real time from the Travel's display. Using the TorqTrac App you can even read the remaining range from a map on your smartphone.

Torqeedo electric inboard and outboard engines

When they founded Torqeedo, concepts such as clean tech and electromobility had not yet been coined. But it was already obvious back in 2004 that electric motors would become increasingly important in the future due to global population growth, the growth of the middle classes around the world, limited oil reserves and efforts to limit global warming.

And since a good idea is also an obligation – the lack of competitive products on the one hand and the future significance of electric propulsion systems on the other gave rise to Torqeedo.
